Did you get this sorted Rob?

Did you get this sorted Rob?

Nope, it's a complete **** up. My easy-out broke off in the hole. Tried cutting slots but no use, welded some 20 bolts to it but they just twist off and if anything has made it worse. So I don't think I have any alternative at this stage but to take it all apart, split the case and try and attack it from the inside :cry:

Post a picture of what you have .You can also try knocking the easy out from side to side using a small centre punch to loosen it.A die grinder with a small stone might remove the easy out .Sounds like work but rebuilding the engine may actually be quicker and less risk of doing damage ,especially if you try and drill it while the case is still together.Downside to dissmantling is you could end up replacing more stuff unless the engine is very low mileage.
I know this kind of thing can be frustrating but keep your spirits up 😎

Personally if its really stuck i would just get on a strip it .A couple of hours and it will be in pieces .you could then try with a small punch to knock out the easyout from behind,but unless you have a large drilling machine or acces to a milling machine dont try and drill it yourself.the case needs to be clamped rigid ,Take it to a machine shop as they will be used to this kind of thing .

Good luck

Post a picture of what you have .

Yep, I was originally reluctant to do any drilling as I didn't want the bits to fall inside. But if I take it apart, knock the easy out -out, then I could maybe drill the hole bigger and then try a larger easy out that is less likely to break (hopefully)  DSC00188.jpg You have insufficient rights to see the content.

A bit of a long shot...

I cant picture how the block is layed out in this area, but could you get somthing down the fuelpump pushrod hole, behind the stud? So you could stop any metal from drilling falling into the engine.

Another idea, worth trying drilling the centre (not through) and wedging in a drill bit or something, then you can get mole grips on to get it turning?

---

Trouble is that the easy out is hardened, so there's no chance of drilling it - it needs to come out somehow

---

Just check for some hardened drillbits. I drilled out a threadtap (or what they are called) with a Bosch hardmetal drill that I found form the local supermarket. I was surpriced on how good those drills are. I even can drill in the coldpressed cheramic plates where normal cheramic drills just burn.. :shock:

I bought some of these from B&Q they really are very good.

Well a friend said something to me this morning - 'out of all bad comes some good', this was going round in my head all day - followed by some swearing etc...

Now I have the case apart, and it turns out that on my case - the distributor screw just goes into solid metal, so it wouldn't return oil anyway :evil: Obviously I did a load of reading before I started and didn't see anywhere that said this might be the situation. So now in addition to getting the distributor screw out, I'll have to sort out some other oil return. Fuel pump bolts go through into the case, or I've seen one Okrasa that had the oil return into the generator stand which also might be an option.

Yep you can simply drill and tap the pedestal.

---

Blind hole would explain why it broke in the first place.Now the case is apart it might be worth thinking about tapping the case for full flow .

Picked up my case from the machine shop this morning, all fixed. Looks like they heli-coiled it. So looks like I'll be busy tomorrow trying to get back on track.

Hopefully there will be no more expensive cock-ups along the way :roll:

Still need to figure out where the oil is going to go back in the case now that I know I can't use the distributor stud. I was thinking about the side of the pedestal, but have been told it's not a good idea because the metal gasket at the bottom of it will slow the oil returning. Need to find other later cases with Frams fitted to find out what they have done...

---

Wouldn't it be possible to return the oil in the oilpressure sensor hole? In that case you could replace the type-1 doghouse oilcooler with a type-3 oilcooler instead. They are basically the same just one difference. The type three coolers have a mountinghole for the oilpressure sensor instead of having it in the case... ;)

Or you could use that hole for return? Don't know if it works, just giving you some ideas? :)

Like this: ;)

No because that's where the oil comes from to go into the filter...

---

Why cant you simply drill/tap the hole for the distributor clamp?

Also, I have seen oil return lines go through a hollow generator pedastal stud...?

That's the one I snapped off, it doesn't go through to the inside - there's a big lump on the inside by one of the main bearings. The early cases must be slightly different there.

I started suspecting that while writing my previous post. Just thought I'd post it anyways. Why not mount a type-3 oilcooled on it then just for the return? Or maybe you will be filtering the same oil over and over again without returning it into the enginecase again... :lol:

Oh, as you say im sure ive seen this work before, but I think it was 30 horse. After typing that, yes, have just found it on Oval56's 30 horse.




And another...



I cant find (yet) any photos of a hollow generator stand stud. I think it is how it will be returing on this rather blurry Okrasa 34 horse engine.

Here you go, Vicpolky's '65 1200 ('64 coded case), oil return from Fram going through a pedastal stud. :wink:

Mr Wob oil lines plumbed in...
